A VPN creates an encrypted tunnel between your device and a VPN server. That matters most when the network between you and the wider internet is not fully trusted. On public Wi-Fi, for example, a VPN can reduce the amount of local visibility into your traffic. It does not make you anonymous, but it can improve privacy in the exact place where many users need it.
For beginners, the main value is not technical vocabulary. The value is knowing when a VPN is worth the extra step and when it is not. If you are checking email or work tools on shared Wi-Fi, VPN is a sensible habit. If you are already on a trusted home network and the task is routine, the upside may be smaller. If your device is badly outdated or your passwords are weak, VPN is not the fix for that problem.
